Mercedes-Benz GLC 300 years to avoid (and the best years)

Which Mercedes-Benz GLC 300 years should you avoid?

No Mercedes-Benz GLC 300 model year stands out from the others in NHTSA owner complaints. The typical Mercedes-Benz GLC 300 year has 37 complaints on file. The busiest years are the 2018 (87) and 2020 (69).

What are the best Mercedes-Benz GLC 300 years?

The Mercedes-Benz GLC 300 years with the fewest complaints on file are the 2022 (31), 2021 (43) and 2019 (47). Model years after 2023 are left out: they have not been on the road long enough to compare.

NHTSA does not publish sales figures, so these are complaint counts, not a rate per car on the road. A year that sold more cars collects more complaints, and older years have had longer to collect them.
